PLUTO Manga

From Amazon.com:
Any pairing of two masterminds can elicit murmurs of approval—or of apprehension. But all readers can rest assured that in this case, the pairing of seinen manga suspense master Urasawa and legendary cartoonist Tezuka is a very, very good thing.

In a distant future where sentient humanoid robots pass for human, someone or some thing is out to destroy the seven great robots of the world. Europol’s top detective Gesicht is assigned to investigate these mysterious robot serial murders—the only catch is that he himself is one of the seven targets.
